How to dissolve a corporation in South Dakota

What does it cost to dissolve a corporation in South Dakota?

South Dakota is inexpensive on the filing side. The Secretary of State charges a modest fee for a corporation's Articles of Dissolution, commonly a few tens of dollars, with online filing available. Confirm the current amount, since corporation fees can differ from LLC fees. South Dakota is also one of the few states with no general corporate income taxso the tax side of a closure here is unusually light.

Fees change; we confirm the current figure with the Secretary of State before we file. See the wider picture on the main corporation guide.

How do the board and shareholders approve dissolution?

A South Dakota corporation dissolves through its governance structure in two moves. First, the board of directors adopts a resolution recommending dissolution. Second, the shareholders approve it, generally a majority of the shares entitled to vote, unless the articles or bylaws set a higher threshold.

Record both the board resolution and the shareholder approval in writing. Even a single-shareholder corporation completes both. That written record supports the Articles of Dissolution and confirms the dissolution was authorized.

How do you dissolve a South Dakota corporation, step by step?

1. Board resolution to dissolve. The directors recommend dissolution, recorded in the minutes.
2. Shareholder approval. Shareholders vote to approve, generally by a majority of shares, recorded in writing.
3. File the Articles of Dissolution. File with the South Dakota Secretary of State, online or by mail.
4. File IRS Form 966 within 30 days. The Corporate Dissolution or Liquidation form, filed within 30 days of adopting the resolution or plan.
5. Wind up the business. Notify creditors, settle or provide for debts, collect receivables, and distribute anything left to shareholders, creditors before shareholders, always.
6. Close state accounts and file the final federal return. Close any South Dakota Department of Revenue accounts, file the final federal return marked final, and close the IRS business account.

The Articles of Dissolution

A South Dakota corporation files Articles of Dissolution with the Secretary of State. The document names the corporation and confirms the board and shareholders authorized the dissolution. South Dakota supports online filing through its business services portal as well as by mail.

Does South Dakota require tax clearance first?

South Dakota does not run a tax-clearance gate the way clearance states do, and it is one of the few states with no general corporate income tax on most businesses. A corporation that collected sales tax still closes its South Dakota Department of Revenue accounts, but there is generally no state corporate income return to file. That makes South Dakota one of the lighter states on the tax side, the federal steps often carry most of the work. Confirm your specific accounts before assuming there is nothing to close.

IRS Form 966 and final returns

Form 966, “Corporate Dissolution or Liquidation,” is the federal filing unique to corporations closing down. A dissolving South Dakota corporation files it with the IRS within 30 days after the board and shareholders adopt the resolution or plan to dissolve. Because that clock runs from the approval, not from your state filing, it is easy to complete the South Dakota side and forget the federal one.

A dissolving corporation also files a final federal income tax return with the “final return” box checked, Form 1120 for a C-corp, Form 1120-S for an S-corp. Because South Dakota has no corporate income tax, this federal return is usually the main tax document. We cover the whole federal sequence on the final tax return page.

How do you wind up a South Dakota corporation?

Winding up is the phase between authorizing dissolution and the corporation legally ceasing to exist, and its cardinal rule is the same in South Dakota as everywhere else: creditors before shareholders. You notify known creditors, settle or set aside funds for the corporation's debts from its assets, collect what is owed to the company, and only then distribute anything remaining to shareholders according to their shares.

Getting that order wrong has consequences that land on people. Distributing to shareholders ahead of creditors can expose them to clawback and can undermine the liability protection the corporate form was meant to provide. If the corporation is insolvent, owing more than it owns, or faces contested claims, that is the point to bring in an attorney rather than a filing service. The safe sequence and the personal-liability traps are laid out on dissolving an entity with debts.

Your EIN and the IRS account

Here is the step almost everyone misses: the EIN. The IRS does not cancel an EIN. The number is permanent and never reassigned. What you do instead is ask the IRS to close the business account behind it, and the IRS will not close it while final returns are outstanding. The South Dakota filing gives the IRS no signal at all.

How long does it take in South Dakota?

The paperwork is quick to prepare, and South Dakota online filings are often processed quickly, sometimes within a few business days, though times vary with the queue. Form 966 and the IRS account closure run on the federal clock, generally several weeks each and independent of the state filing.

Confirm current Secretary of State processing times before relying on a date.
